Abstract

Background: Atrial fibrillation (AF) is one of the most important risk factors for ischemic stroke. Atrial fibrillation in stroke patients can be classified as: 1. previously known atrial fibrillation that was detected before the stroke occurred and 2. newly diagnosed atrial fibrillation, detected after the stroke occurred (AF de novo). The aim of this study is to analyse the severity and outcome of stroke in patients with newly diagnosed AF and those with known AF.
Materials and Methods: A retrospective analysis was made of 98 patients with acute stroke with AF hospitalised at the University Clinic for Neurology in Skopje, North Macedonia - at the Department of Urgent Neurology in the period from 2019 to 2022. Inclusion criteria for the study were patients with AF, in all age groups, diagnosed with stroke. In the analysis, we also included other parameters such as neurological deficit quantified by NIHSS (National Institutes of Health Stroke Scale), state of consciousness quantified by GCS (Glasgow Coma Scale/Score) and degree of disability quantified by mRS (Modified Rankin Scale).
Results: The results of this study showed that group 1A (known AF) patients had a predominance of moderate to severe stroke (quantified by NIHSS score), moderate disability (quantified by mRS score), low GCS score, compared to group 1B (AF de novo) patients with a predominance of mild stroke, mild disability, but without proven statistical significance (p>0.05).
Conclusion: We found that stroke severity and scores quantified by NIHSS, GCS, and mRS in patients with newly diagnosed AF did not differ from those in patients with known AF.
